Revenge
I leased a '94 Jag. Before very long I started having trans trouble. After several attempts at repairs, including one attempt where they charged me and had to pay me back because their 'fix' didn't work, they finally decided that they'd have to do a complete rebuild---for $2300. I concluded that the problem couldn't be mechanical, and after searching, got a set of wiring diagrams. After study, I went to the local parts store and bought a Chrysler relay. When I plugged it into the socket on the firewall it cured the problem---for $6 and change. Installing the relay took about 30 seconds.
Several months later the head gasket blew. This time they told me $3500. Since I didn't trust them I decided to do it myself. But to do something that complex, I needed to get into a garage and I didn't have one at the time. So I offered an acquaintance $300 to help---and use his garage. When we got the head off, we discovered that the head had been over-torqued. The fire rings around two adjacent cylinders had been crushed into the aluminium head, creating a space that wasn't sealing properly and gave out.
I had the head cut to remove the damaged surface, and we put it all back together. Then I called Jaguar and told them they owed me $1100 for the repair. (I paid myself for the work I'd done as well as the parts and labor. It seemed to be a good deal for them since that was less than a third of what it should have cost.)
That started a ruckus that went on for about two months, and ended when one of their customer relations guys told me for about the tenth time that they weren't going to pay me anything and to---and I quote, "Go :q:q:q:q yourself!"
To make the rest of the story as short as possible, I sued them, doing all the work myself. It actually cost me about $50 for the filing fees. By the time it really got going, (and because I'd sued everybody who was even remotely connected) there were lawyers from five different law firms opposing me. I never paid another penny to Jag Credit, and mostly left the car locked up at a friends house. More than two years later, (and after going through three judges in two different suburbs here locally), a judge finally told me I had to give it back. One of the attorneys opposing me told me after a court session that by that time it had cost over $80 thousand in legal expense to my opposition. And it was more than a year after that when I gave it back. They tried every legal trick to keep me from having an actual hearing about my $1100. And I had become content to just keep it going and costing them money. I got a new Town Car to drive while this was going on.
I finally got tired of the whole thing and just let it drop. And right after that was when I gave the car back. They didn't even try to get any money from me for either their outlay for lawyers or the two years I kept their car locked up.
So I'm not sure they'll fix your car. But you CAN make it very costly for them to turn you away!
